[Formula]

Hello to all. I am in need of some help... I have a 1993 Firebird Formula with the LT1 and it just wont start. It has something to do with the wiring to the icm. It wont spark from the coil unless I use a test light to poke the white wire going into the icm? I have no Idea why this is but when I poke it with the test light and someone cranks it will usually start. If I totally ground the wire it wont spark at all. This is my 3rd icm I have installed on this car. I think maybe its getting too much voltage when its being cranked? Any advice would be great. Thanks

If it starts with you messing with the wire have you checked that wire for continuity?
